+    aa-remove-unknown: fix readability check
+    
+    This check is intended for ensuring that the profiles file can actually
+    be opened.  The *actual* check is performed by the shell, not the read
+    utility, which won't even be executed if the input redirection (and
+    hence the test) fails.
+    
+    If the test succeeds, though, using `read` here might actually
+    jeopardize the test result if there are no profiles loaded and the file
+    is empty.
+    
+    This commit fixes that case by simply using `true` instead of `read`.
